I Application filed September 3, 1884. ()To model.)

' To (ZZZ whom, it may concern.-

budding knife, implement, or'tool; audit consists,essentially,in a concavo-convex or gougeshaped' blade having its forward end reduced to a cutting-edge, said blade being adapted to cut the stock crosswise and raise the bark, and in a fiat blade set edgewiselo'ngitudinally on the convex surface of the concavo-con'vex blade and having its forward end reduced to a cutting-edge adapted to make the longitudinal cut in the stock.

It further consists in details connected with each blade, whereby they are fitted together and to a suitable handle, all of which I shall hereinafter fully explain. y

The object of my invention is to provide a simple and effective buddingknife adapted to make all the necessary cuts in the stock and to raise its bark by asingle continuous operation.

Referring to the accompanying drawings, Figure 1 is a perspective view'of my buddingknife, showing its use. Fig. 2 is a perspective view of the budding-knife. Fig. 3 is a front or end View of same.

A is the handle or stock, made of suitable material, preferably of bone or horn, and of any convenient shapein crosssection. In one end it may have an ordinary pivoted blade, B, adapted to be opened and closed in the usual manner. In its other endit has an internallythreaded socket, a.

G is a piece or bar of metal, the body of which is preferably semi-cylindrical in crosssection, the rear end or shank, c, cylindrical and externally threaded to fit the threaded socket a, and its forward end cut or hollowed out to form a corfd'avo-convex or gougeshaped blade, 0, the end of which is rounded and reduced to a cutting-edge.

In the back or convex surface of piece 0, extending its whole length, including blade 0, is made a groove, 0 in which is fitted the back of a flat blade, D, having a cutting-edge along its top and at its rounded point or end. This blade is set so that its forward end lies about flush with the forward end of the blade 0; but as this latter wears the knife D is adapted to beset back to its proper position by sliding it along in its grooved bed. It is fixed in any position by means of a clamping-sleeve, E, embracing the body of piece 0 and provided with ears 6, between which the rear of the blade fits and is secured by a set-screw, e. By setting up this screw the sleeve is clamped to its seat and the blade D held in position. By loosening the screw the sleeve is loosened and the blade may be readjusted, and by removing the screwthe blade may be entirely separated, if required.

The use of my knife is as follows: The bud is cut from its placein the usual manner, which may be accomplished by the blade 'B in the end of the handle; or, if preferred, by the cuttingedge of blade D, in which case the implement will not have to be turned end for end. The tool is then grasped, and while held at an angle-say of about forty-five degrees or more-is pressed down upon the stock, as shown in Fig. 1, the end of blade cbeing crosswise of the stock, until its cutting end and the cutting end of the blade D both pierce the bark and bear against the wood. The tool is then lowered to a smaller angle and pusheddown the stock, whereby the end of blade D makes the longitudinal out, While on each side of it the back of the blade 0 raises the bark, its sharp edge easily separating the bark from the wood as it advances.

It will be observed that the cross-cut, the longitudinal cut, and the lifting of the bark are steps in one single and continuous operation, and can therefore be accomplished rapidly. The changing of the angle of the tool is easily and quickly done. It will be seen that the blade 0 is made of some length. The

both in length and width it forms a guide which renders the operation of the tool as accurate as possible. The rounded ends of bothbl'ades prevent them from catching or being otherwise impeded. lhe purpose of flattening the under side of the body of piec'e Gis to do away with much of a shoulder at the, line where it joins the blade 0, and thus allow the tool to be lowered to a small angle with the stock as it is about to be moved forward, and yet not strike or bruise the bark.

As I have before stated, when the blade c becomes worn on the end, the blade D maybe adjusted correspondingly.

I might secure the piece 0 to the handle by an ordinary pivot and adapt it to open and close, similar to the action of the blade 13;. but Iprefer to screw it in as shown, as'it permits its ready removal for the. substitutionof another of a different size. 7

Having thus described my invention, what I claim as new, and desire to secure by. Letters'Pat'ent,-is

I. Ina budding knife, implement,, or tool, a concave-convex or gouge-shapedbladehavingits forward end curved and reduced, to a cutting-edge, and aflat. blade secured edgewise longitudinally on the con-vex surfaceof the concavo-convex blade and havin'git'sforward end approximately flush with thelforwarde nd-of s'aidblade curved andredu'cedto a cutting-edge,substantially as herein described.

2, In a budding knife, implement; or tool,

' a concavo-convex or gougershape'd blade-having. its, forward end reduced to acutting-edge,

and a flat blade secured-on edge longitudinally on the convex surface of the concave-convexblade and} adapted to ,be adjusted longitudinally thereon, said flat blade having its'forward end r'educed'to a cutting-edge, substan- T tially'as'. herein described.

3i Ina budding knife, implement, ortool, the". concave-convex elon gated blade, 0, havi nfgi 5 its forwardend reduoed to a cutting-edge, in

longitudinally in the convex surface of the blade 0 and continued in the surface of the bodyof piece 0, the clamping-sleeve E, embracing the piece Gand blade D, andthe setscrew e through the sleeve and blade D, whereby said blade may be' fixed where adjusted, substantially as herein described.

5. In a budding knife, implement, or tool, the piece or bar G, having a. semi-cylindrical body and a concave-convex blade, 0, as described, in combination with theflat blade D ion. the back of thebody of the. pieceor bar, and of the blade a, substantially ashereimderscribed. Y L 6. A budding knife, implement, or too1,.con-

sisting of the. handle A, having a threaded socket, a, in one endtthe. piece or bar 0,; having a threaded shank, 0, adapted to enter socket a, and the. concave-convex or gouge, shaped blade 0, formed withsaidpiece .or. bar

. andhaving a cutting; edge on it'sforward end, said blade being. adapted. tov cut the. bark of thestock crosswise and raise .it, andl the adjustableflat blade D, set on itsback longitudinally on the convex surface of the blade:.c,and

having its forward end reduced to a cutting.-

edge adapted to-' make the longitudinal. cut in. the stock", substantially as hereindescribed.
